I got into HEMA (Historical European Martial Arts) fencing last year through a club in my little town. Olympic/sport fencing is fun, but imagine (safely) swinging a 4lbs. steel longsword with two hands at your opponent instead. It's a ton of fun, a great workout (I burn ~1500 calories per class), and competitive so it keeps my interest. Then there's the whole nerd layer of reading all the original sources from the 15…

#472Synthesizers! I like it because it's tactile and immediate, and you're not glued to a screen, but can create fun-sounding beats. Nowadays there are nice, cheapish groove boxes that are perfect for noodling on the couch. I started with the Novation Circuit Tracks, and also really enjoy the Teenage Engineering EP-133. Not to say that I am any good at this, but it's an enjoyable hobby! Bonus if you are friends who are a…
Deep in the Eurorack rabbit hole myself. Trying to avoid anything that has a screen and anything that requires a computer to interact with. Patching cables and twiddling knobs is great fun. Sometimes it even sounds good xD
The only slight downside is I often do it on my own away from the family.

#473Get a microscope and help me explore the role of structured water in rouleaux formation. Rouleaux formations are clumps of red blood cells, and they're bad because 90% of our circulatory system is I did an n=5 study on sauna and rouleaux (positive result; draft report: https://thespacebetween.xyz/p/sangre-y-sauna/ ), and some n=1 observations of myself with grounding and wifi.

What is structured water?
> Hexagonal water, also known as gel water, structured water, cluster water,[1] H3O2 or H3O2 is a term used in a marketing scam[2][3] that claims the ability to create a certain configuration of water that is better for the body.[4]
> The concept of hexagonal water clashes with several established scientific ideas. Although water clusters have been observed experimentally, they have a very short lifetime: the hydrogen bonds are continually breaking and reforming at timescales shorter than 200 femtoseconds.[7] This contradicts the hexagonal water model's claim that the particular structure of water consumed is the same structure used by the body.

Frankly this is a bit of a red flag for me in terms of scientific rigour. It sounds like you want the conclusion to be true, or you already believe it to be true, that EMFs are harmful, and you are searching for ways to justify it. Careful with confirmation bias.
> would also make the benefits of sauna, red light therapy, grounding/earthing, and other practices more legible
This is also a bit suspect. These treatments don't seem to have much in common and it's unclear how they may affect the phenomenon you are discussing. Coincidentally they also tend to be some of the go-to treatments for a myriad unscientific wellness practices.
And I'm not sure how you plan to observe the molecular structure of water with a basic microscope. I suppose that trying to induce Rouleaux formations by exposing red blood cells to WiFi is worth a try of course, but it would be very strange if such a basic thing hadn't been observed already by the scientific community.

Yeah okay... Surprised to see this as the top comment. > Hexagonal water, also known as gel water, structured water, cluster water,[1] H3O2 or H3O2 is a term used in a marketing scam[2][3] that claims the ability to create a certain configuration of water that is better for the body.[4] > The concept of hexagonal water clashes with several established scientific ideas.

#477Get your Part 107 federal drone license and volunteer for your local fire department or search and rescue. When the FD responds to structure fires they sometimes have to go up on the roof to cut an air hole. This allows oxygen into the building which helps prevent backdrafts. A FLIR equipped drone can help direct the hole cutter around hotspots on the roof. If your local fire department has a drone, it might not have…
How involved is the license? I've flown racing quads and RC planes, so I think I have the hand-eye coordination and spatial awareness skills. Is this something that would be saturated in the Bay Area? Does the SAR team provide the drone?
I'm not sure how saturated it would be. My advice would be to contact the closest FD (or PD if you wanted to go the SAR route) and ask. If they say they're covered, ask if they know any other stations that could use a hand. There's bound to be a department that needs volunteers.
The FD should have an enterprise level DJI (or equivalent) with color and IR cameras but it will probably depend on how well funded the department is. SAR may be a different story as far as equipment but I don't know since that's not the route I pursued.

#478Flying sailplanes/gliders. Once you get good at it, you can fly hundreds of miles (or more) by understanding the weather and figuring out where the air is going up. Lots of opportunities to nerd out. Aerodynamics, weather forecasting, remote sensing, in-flight user interfaces, strategy, communications, and also just satisfying to figure out how to coax the atmosphere to get you somewhere for free.
I did a few flights in college but never got my license because there wasn’t an instructor light enough to meet weight requirements with me lol. Do you have yours? If so, how long did it take you?
Weight wise I was skinny back then and it wasn’t a problem. I soloed my first full year and got my license the next year.

Though funnily enough, you can make real 'structured water' at home in your freezer. Making your ice crystals hexagonal is theoretically possible, but it's really, really hard to grow monocrystaline water ice. That might be a really interesting niche hobby, though. See https://www.youtube.com/watch?v=VA710QYxEu0 for the latter.
If “structured water” just means that there are tiny ice crystals in water, sure that’s very plausible, but I doubt it would have much of an effect.
PS: Trying to grow crystals of different challenging structures does sound like an awesome hobby.

#480Something is stuck within my body most of the time.
Doing certain movements makes this something flow better.
I feel better when this happens.
Breathing in certain ways enhances this something.
I feel A LOT better when this happens.
Still early, exploring.
